In lava: Latent Variable Models

Calculate diagnostic tests for 2x2 table

Description

Calculate prevalence, sensitivity, specificity, and positive and negative predictive values

Usage

diagtest(
  table,
  positive = 2,
  exact = FALSE,
  p0 = NA,
  confint = c("logit", "arcsin", "pseudoscore", "exact"),
  ...
)

Arguments

table	Table or (matrix/data.frame with two columns)
positive	Switch reference
exact	If TRUE exact binomial proportions CI/test will be used
p0	Optional null hypothesis (test prevalenc, sensitivity, ...)
confint	Type of confidence limits
...	Additional arguments to lower level functions

Details
